Cargo Features

[dependencies]
mcl = { version = "0.5.0-alpha", default-features = false, features = ["serde_lib"] }

default = serde_lib

The serde_lib feature is set by default whenever mcl is added without default-features = false somewhere in the dependency tree.

serde_lib default = serde

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
